Specification of Letters Patent.

Application filed November 17, 1910. Serial No. 592,885.

To all whom it may concern:

Be it known that I, EDWIN JOHN CHIL- TON, a citizen of the Dominion ofNew Zealand, and resident of Kuripuni, Masterton, in the ProvincialDistrict of Wellington, in the Dominion of New Zealand, have inventedcertain new and useful Improvements in Sanitary Flushing Apparatus, ofwhich the following is a specification.

The invention relates to apparatus for flushing water closets and thelike.

According hereto, a ball valve within a casing in the down pipe, israised from its seat by a lever and the contents of a flushing cisterndischarged. The ball is kept off its seat by the pressure of the flowingwater upon a wing plate which has an arm in contact with the ball. Thecistern is closed at the top and the supply of water thereto, beyond apredetermined quantity, is prevented by a float which closes an airvalve. Noise is prevented by a cap operated by a ball float and arrangedto close the downpipe before air can obtain admission thereto.

My invention is illustrated in the drawing wherein:-

Figure 1, is a vertical sectional View through an embodiment of theinvention; Fig. 2, a similar view taken on a plane substantially atright angles to that of Fig. 1. Fig. 3, is a plan View. Fig. 1, is asectional elevation of the cistern and parts.

Referring to the drawings, the ball 1 normally rests upon the valve seat2 and closes a passage 3 in the casing a which is located in thedownpipe 5. A crank arm 6 adapted to lift the ball from its seat isfixed upon a spindle 7 which passes through a stufling box 8 and isjournaled in the casing. A wing plate 9 pivoted to a bracket 10 isintegrally formed with a curved arm 11 the end of which rests upon theball.

Upon the spindle 7 being partially rotated by a hand piece 12 the ballis lifted from its seat by the arm 6 into a recess 13 and is maintainedtherein (so long as water is flowing through the downpipe) by the arm 11which is held against the ball by the pressure of water upon thewingplate.

A by-pass aperture 14: is closed by a valve 15 which is guided by aslide 16 working in a cylinder 17. A coiled spring 18 is interposedbetween the guide and a cap 19 screwed upon the end of the cylinder. Aneccentric cam 20 fixed upon spindle 7 engages a projection 21 from thevalve when the spindle is partially rotated and lifts the valve from itsseat. In order to reduce pressure upon the ball 1 and thereby facilitateits opening the Valve 15 is lifted by the cam before the crank arm 6contacts with the ball.

Referring now to Fig. 4, the cistern 22 is connected to a supply pipe 23and has a closed top 24 in which is an air valve 25 closable by a float26. When water in the cistern has risen to a certain height the airvalve closes and shortly thereafter pressure of air, prevents furtheringress: of water. The passage through the supply pipe is restricted sothat when the bypass valve referred to is opened the water falls belowits normal level, the air valve opens and pressure in the cistern isreduced. Upon the top of the downpipe 5 slides a cover cap 27 operatedby the lever 28 pivoted at the end 29 and having a ball float 30 at theother. When suflicient water has passed out of the cistern the ballfloat falls, the cap slides upon the downpipe, and covers a number ofholes 31, thereby closing the downpipe before noise can be caused by airrushing into it.

hat I do claim and desire to secure by Letters Patent of the UnitedStates is 1. In a flushing apparatus, the combination of a casing orconduit, a valve normally closing the passage through the casing, aby-pass for conducting water about said valve, a supplemental valvenormally closing the by-pass, a spindle provided with radiallyprojecting means adapted to successively move said supplemental and mainvalves from their seats as it is rotated, and means for turning thespindle.
